Open Up Your Roof To The Outdoors
The Glazing Vision Sliding Over Roof Rooflight features an entire glazed section that smoothly slides out onto the tracks installed on your roof space, leaving you with clear, uninterrupted views of the sky above. When closed, its large glass surface and minimal framework keep the focus on daylight and views, helping you feel connected to the outdoors even on rainy Irish days.
Sliding rooflights bring a unique feature to any home or workspace. At the touch of a button, you can open up almost the entire ceiling to fresh air and natural light, creating a living environment that changes with the weather and seasons. When opened, the weight of the sliding section is fully supported by discreet roof tracks for smooth, reliable operation.
For larger openings or bespoke projects in Ireland, we can design and manufacture a custom Sliding Over Roof Rooflight, which may include internal supports such as aluminium angles or glass fins to maintain strength.
